Available in PDF, EPUB and Kindle. Book excerpt: Tumor-associated immune cells, in particular myeloid cells, have opposing roles during cancer development by facilitating antitumor immune responses and driving cancer-promoting inflammation. Defective antitumor immunity is prevalent in cancers, and it is now clear that overcoming the myeloid cell-mediated immunosuppressive microenvironment poses tremendous interest for future cancer therapies. JAK/STAT signaling has come to the forefront as a crucial pathway to induce immunosuppression and procancer inflammation. Specifically, STAT3 activation is critical for the phenotype of myeloid cells by regulating immunosuppressive and prometastatic factors, thereby providing myeloid cells with a multitude of tumor-promoting functions. Genetic ablation of STAT3 in the myeloid compartment induces potent innate and adaptive antitumor immunity along with an inhibition of tumor growth and metastasis. Recently, therapeutic targeting of JAK/STAT3 has shown great promise in blocking immunosuppression in preclinical models. One such example is the use of novel siRNA to selectively target STAT3 in myeloid cells, through conjugation to CpG oligonucleotides that agonize Toll receptor TLR9 on myeloid cells. Along with other novel therapeutic strategies to inhibit JAK/STAT signaling, it seems likely that future efforts to target this pathway will be made in single and combination approaches for effective anticancer immunotherapy.

This book was released on 2014-02-10 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tumor-Induced Immune Suppression - Prospects and Progress in Mechanisms and Therapeutic Reversal presents a comprehensive overview of large number of different mechanisms of immune dysfunction in cancer and therapeutic approaches to their correction. This includes the number of novel mechanisms that has never before been discussed in previous monographs. The last decades were characterized by substantial progress in the understanding of the role of the immune system in tumor progression. Researchers have learned how to manipulate the immune system to generate tumor specific immune response, which raises high expectations for immunotherapy to provide breakthroughs in cancer treatment. It is increasingly clear that tumor-induced abnormalities in the immune system not only hampers natural tumor immune surveillance, but also limits the effect of cancer immunotherapy. Therefore, it is critically important to understand the mechanisms of tumor-induced immune suppression to make any progress in the field and this monograph provides these important insights.
Download or read book Myeloid Derived Suppressor Cells and Cancer written by David Escors and published by Springer. This book was released on 2016-03-15 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book starts with an introduction to and history of myeloid-derived suppressor cells (MDSCs), followed by a description of their differentiation, their role in the tumour microenvironment and their therapeutic targeting. It closes with an outlook on future developments. In cancer patients, myelopoiesis is perturbed and instead of generating immunogenic myeloid cells (such as dendritic cells, inflammatory macrophages and granulocytes), there is an increase in highly immature MDSCs. These cells are distributed systemically, resulting in general immunosuppression. They also infiltrate tumours, promoting their progression and metastasis by inhibiting the natural anti-tumour immune response. As these cells also interact with classical anti-neoplastic treatments, they have become major therapeutic targets in the pharmaceutical industry and in oncology research.

Download or read book Myeloid Derived Suppressor Cells as Disease Modulators written by Olivera J. Finn and published by Frontiers Media SA. This book was released on 2020-05-06 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: Myeloid Derived Suppressor Cells (MDSCs) are a heterogeneous population of immature myeloid cells that can suppress the function of multiple immune cells and in particular, T cells, through various mechanisms. MDSCs can be divided into two major subtypes based on their cell surface phenotype and morphology: polymorphonuclear MDSC (PMN-MDSC or G-MDSC) and monocytic MDSC (M-MDSC). Additional subtypes have been proposed, such as the early MDSC (e-MDSC) that lack both macrophage and granulocyte markers. There is still considerable ambiguity about the phenotype of these cells that corresponds to their immunosuppressive function and there are on-going challenges on how to identify, purify and/or potentially generate and expand these cells in vitro. MDSCs were first discovered in cancer patients where they have been most extensively studied as components of the immunosuppressive tumor microenvironment. In the last several years, however, the importance of their immunomodulatory role in many other disease and clinical settings has emerged.

Download or read book Cancer Immunotherapy written by Suzanne Ostrand-Rosenberg and published by Elsevier Inc. Chapters. This book was released on 2013-06-04 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: Immune escape and inflammation are now recognized as hallmarks of tumor onset and progression. Myeloid-derived suppressor cells (MDSC), a heterogeneous population of immature myeloid cells that are present in virtually all patients and mice with advanced cancer, are a major contributor to immune escape through their inhibition of innate and adaptive antitumor immunity. Immature myeloid cells with the phenotype of MDSC are present in low levels in healthy individuals; however, chronic inflammation perturbs normal myelopoiesis and mobilizes MDSC, thereby facilitating tumor growth. This chapter reviews the experimental and patient findings that identified MDSC as an immune suppressive cell population mediating tumor immune escape, the phenotypic characteristics and heterogeneity of MDSC from cancer patients and mice, the diversity of mechanisms used by MDSC to facilitate tumor progression and metastasis, the pro-inflammatory mediators that drive the induction and accumulation of MDSC, and therapeutic approaches that have been developed to reduce MDSC levels and/or impair MDSC function.
Download or read book Tumor Microenvironment and Myelomonocytic Cells written by Subhra Biswas and published by BoD – Books on Demand. This book was released on 2012-03-30 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tumor microenvironment represents an extremely dynamic niche shaped by the interplay of different cell types (e.g. tumor cells, stromal cells), their soluble products (e.g.cytokines, chemokines and growth factors) and varied physico-chemical conditions (e.g low oxygen concentration or hypoxia). Recent studies have identified myelomonocytic cells as key players in regulating the tumor microenvironment and hence, tumor progression in a variety of cancers. In view of these findings, the present book attemps to provide a comprehensive account of the diversity of tumor microenvironment across different cancers and how myelomonocytic cells have taken the center-stage in regulating this niche to direct cancer progression. A better understanding of the myelomonocytic cells and the mechanisms by which they regulate cancer progression will open new vistas in cancer therapeutics.
Download or read book Understanding convergent evasion mechanisms in cancer and chronic infection Implications for immunotherapy written by Matthias Theobald and published by Frontiers Media SA. This book was released on 2024-06-04 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: The complex interactions between the innate and adaptive immune systems function to recognize and clear pathogens or transformed cells, but inefficient interactions between these two systems can result in harmful immunologic responses including chronic infections and the development of cancer. Several hallmarks of dysfunctional adaptive immune responses often detected in tumors share specific features with ineffective immunity in chronic infections. The members of the micromilieu actively participate in the process of tumorigenesis or chronification of infection by modulating innate and adaptive immune system interactions leading e.g. to insufficient T cell responses. The best example is given by the acquisition of an “exhausted” state of cytotoxic CD8+ T cells (CTLs) responding to chronic infections or tumors that are associated with elevated expression of inhibitory receptors and impaired cytokine response. Targeting these major inhibitory pathways by immune checkpoint blockers represents a prime example of successful clinical translation of tumor-specific immunotherapies. Understanding the mechanisms behind (mal)adaptations of the immune system is crucial for achieving therapeutic benefits. The establishment and co-evolution of a dynamic microenvironment niche constituted by the recruitment of numerous cell types dampen immune responses and thus contribute to the development of neoplastic transformation as well as infection. Although there are examples of successful immunotherapeutic approaches (CAR-T cells, immune checkpoint inhibitors, or mRNA vaccination), a large percentage of patients with cancer or chronic infections still do not benefit from these therapies or develop severe immune-related adverse events. The reasons for these failures are not well understood. A possible explanation might be that current immunotherapies target predominantly the effector arm of the immune system by trying to reactivate dysfunctional T cells, but do not sufficiently address the influence of the innate immune system and the contributions of the tumor microenvironment (TME) niche. The main problem we would like to address in this special issue is how inappropriate function of the innate immune system affects adaptive immunity and contributes to inefficient anti-cancer immunity and chronification of infections. The central goal is to provide a more precise understanding of the various (common and novel) immune evasion mechanisms in cancers and in chronic infections to obtain a detailed map of common and disease-specific immune escape checkpoints. To that aim, we want to compile a wide array of interdisciplinary studies exploring a comparative and multi-layered analysis of mechanisms responsible for inefficient immune responses, including novel approaches i.e. multi-omics or epigenetic signaling. We would also like to combine studies from different fields, including basic and clinical immunology, oncology, and virology/microbiology. We welcome the submission of Original Research, Review, Mini-Review, Methods, Case report, and Perspective articles that cover, but are not limited to the following topics: • Convergent mechanisms supporting immune escape in preclinical models (tumors and chronic infections) • Convergent evasion mechanisms mediated by tumor-infiltrating suppressive cells (Treg, MDSC, macro-phages, soluble mediators, signaling, metabolism, ...) • Convergent immune evasion mechanisms mediated by chronic infection (viral or parasite) • Novel strategies to modulate the TME by direct or indirect targeting of immune suppressor cells. • Approaches to enhance persistence and resilience of anticancer T cells • Combinatorial therapeutic strategies (mRNA, antibodies, immune checkpoint blockers …) that target convergent immune evasion mechanisms Manuscripts consisting solely of bioinformatics or computational analysis of public genomic or transcriptomic databases which are not accompanied by robust and relevant validation (clinical cohort or biological validation in vitro or in vivo) are out of scope for this topic.

Download or read book Tumor Immune Microenvironment in Cancer Progression and Cancer Therapy written by Pawel Kalinski and published by Springer. This book was released on 2017-12-22 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: The tumor microenvironment has become a very important and hot topic in cancer research within the past few years. The tumor microenvironment is defined as the normal cells, molecules, and blood vessels that surround and feed a tumor cell. As many scientists have realized, studying the tumor microenvironment has become critical to moving the field forward, since there are many players in a tumor’s localized and surrounding area, which can significantly change cancer cell behavior. There is a dual relationship wherein the tumor can change its microenvironment and the microenvironment can affect how a tumor grows and spreads. Tumor Microenvironment in Cancer Progression and Cancer Therapy aims to shed light on the mechanisms, factors, and mediators that are involved in the cancer cell environment. Recent studies have demonstrated that in addition to promoting tumor progression and protecting tumor cells from the spontaneous immune-mediated rejection and different forms of cancer therapeutics, tumor microenvironment can also be a target and mediator of both standard and newly-emerging forms of cancer therapeutics. Thus, the dual role of the tumor microenvironment is the integral focus of the volume. The volume highlights the bi-directional interactions between tumor cells and non-malignant tumor component during tumor progression and treatment. It also focuses on the three groups of the reactive tumor component: stromal cells, blood vessels and the infiltrating immune cells. These three groups are discussed under the lens of their role in promoting tumor growth, shielding the tumor from rejection and from standard forms of cancer therapies. They are emerging as targets and mediators of standard and new forms of potential therapy.
